[PATCH 2/2] fix: evaluate_dereference() unexamined base type

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

Examination of a pointer type doesn't examine the corresponding base type
(this base type maybe not yet be complete).
The examination of thz base type must thus be done later.

However, in some cases (maybe only when typeof() is involved) it's
possible to call evaluate_dereference() while the base type is still
unexamined.

Fix this by adding the missing examine_symbol_type() on the base type.
